The City can determine the relationship of a particular property to the floodplain, including:
1) whether the property is located within the Special Flood Hazard Area;
2) Flood Insurance Rate Map (FIRM) Zone for property;
3) Base Flood Elevation for property, if available; and
4) whether the property is located within the Floodway.
Contact the Ephrata Community Development Department at (509) 754-4601 for further information.
Practical and cost-effective methods for reducing or eliminating the risk of flooding are available to property owners whose homes have experienced damage from flooding in the past, or may experience damage in the future. Such techniques include elevation of the home, relocating the home to higher ground, constructing floodwalls or berms, flood-proofing and protecting utilities. For further information, contact the Ephrata Community Development Department at (509) 754-4601 and the Federal Emergency Management Agency, Region X at (425) 487-4600.
During times of flooding, homes that have not been retrofitted can be protected during emergencies by the installation of sandbags. For further information about sandbags and the locations of sites where sandbags are available during flooding, contact the County's Department of Emergency Management at (509) 762-1462, or visit their Web site at: http://www.grantcountywa.gov/EM/. In case of an emergency, call 911.
Keep banks clear of brush and debris to help maintain an unobstructed flow of water in drainage channels. Do not, however, remove vegetation that is actively growing on a drainage bank. Streamside vegetation is tightly regulated by local, state and federal regulations.
Before undertaking any removal of streamside vegetation, contact the Ephrata Community Development Department at (509) 754-4601 or the Grant County Planning Department at (509) 754-2011.
Please report any observations of the clearing of vegetation or trees on drainageways or stream banks to the City of Ephrata at (509) 754-4601 or Grant County Planning Department at (509) 754-2011.
A plugged channel cannot carry water, and when it rains, the excess water must go somewhere. Trash and vegetation dumped into a stream degrades water quality of both the stream itself and its receiving waters, and every piece of trash contributes to flooding.
The City has adopted and enforces regulations that prohibit the dumping of material into any natural or manmade component of the stormwater drainage system. Additionally, the City as a whole has adopted and enforces regulations that prohibit the illegal dumping of material, including material dumped into ditches, streams or other drainageways.
Please report any observations of the dumping of debris or other objects into drainageways to the City Community Development Department at (509) 754-4601.
To minimize damage to structures during flood events, the City requires all new construction in the floodplain to be anchored against movement by floodwaters, resistant to flood forces, constructed with flood-resistant materials and flood-proofed or elevated so that the first floor of living space, as well as all mechanical and services, is at least 2 feet above the elevation of the 100-year flood. These standards apply to new structures and to substantial improvements of existing structures. The City defines a Substantial Improvement as any reconstruction, rehabilitation, or addition to an existing structure, the cost of which exceeds 50 percent of the structure's appraised or market value (whichever the builder chooses to use). Additionally, most other types of development within the floodplain also require a floodplain development permit, such as grading, cut and fill, installation of riprap and other bank stabilization techniques.
City staff are available to undertake site visits, if requested, to review flood, drainage and sewer issues. Contact the City of Ephrata Community Development Department at (509) 754-4601 for further information and prior to undertaking any activity within the floodplain.
Floodplains are a natural component of the Ephrata environment. Understanding and protecting the natural functions of floodplains helps reduce flood damage and protect resources. When flooding spreads out across the floodplain, its energy is dissipated, which results in lower flood flows downstream, reduced erosion of the streambank and channel, deposition of sediments higher in the watershed and improved groundwater recharge. Poorly planned development in floodplains can lead to erosion, loss of valuable property and increased risk of flooding to downstream properties.
